The dusky clubtail is an unusual clubtail dragonfly that is found in the north eastern half of the United States and up into eastern Canada. It is one of a handful of clubtail dragonflies that does not have any widening at the end of the abdomen. The widened, or club shaped abdomen, which is what clubtail dragonfly are named for is not defining feature which identifies a member of the Gomphidae, clubtail, family. Separated eyes are what make a dragonfly a Gomphid.
The dusky clubtail also prefers a different type of habitat than most Gomphids. Most clubtails are found around fast moving clean water, typically rivers. The dusky clubtail prefers a more stagnant habitat. Habitat like bogs, Lakes and slow moving streams with a sandy bottom are preferred.
